Funny language

Jasper sent me messages on skype with lots of funny language. Can anyone please tell me what was Jasper trying to tell me? Was he trying to take revenge after I posted on facebook the fact that he actually wanted to gain weight by drinking protein milk? LOL.

Sorry, Jasper, you have no more secret because you are a friend of mine!!

This was the conversation which is full of weird language. LOL. I tried to figure out what kind of language is that and use google translate, but I have no idea about it. Please do help me understand!!
